Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical parking equipment, specifically relating to a stacking machine for storing AGV vehicle pallets. Background Technology

[0002] Driven by both accelerated urbanization and the continuous growth in car ownership, planar mobile parking systems have become widely used in various scenarios such as commercial complexes, residential communities, and public parking lots due to their advantages of high space utilization and high automation. These parking systems typically use vehicle carriers as the core carrier for vehicle loading and unloading, forming a complete parking operation system in conjunction with parking garages, car lifts, and AGV parking robots. The standard vehicle parking process is well-established: the driver drives the vehicle onto the vehicle carrier in the parking garage; the car lift then transports the vehicle carrier to the designated parking level; the AGV parking robot, upon receiving instructions, transports the vehicle carrier and car together to the preset parking space; the AGV then returns to the parking space to retrieve the empty vehicle carrier and transport it back to the car lift; finally, the car lift transports the empty vehicle carrier back to the parking garage to prepare for the next vehicle. In this process, the coordinated operation of all devices achieves automated vehicle parking and the recycling of vehicle carriers, supporting the basic operational requirements of planar mobile parking systems.

[0003] A search revealed that CN218092298U discloses a lifting and traversing parking device suitable for a lift-type AGV parking robot, including a traversing device. The lower end of the traversing device is provided with a traversing guide rail. A frame steel structure is fixedly installed on the ground outside the traversing guide rail. A lifting drive is fixedly installed on the upper end of the frame steel structure. A lifting frame is fixedly installed on the lower end of the lifting drive.

[0004] However, existing parking systems require the AGV parking robot to return from the parking space to the car lift after each vehicle is parked. This process not only consumes the one-way transfer time of the AGV parking robot but also involves the additional step of transporting empty car pallets back to the parking garage by the car lift. This results in a long waiting period for the replenishment of car pallets in the parking garage. The process delay caused by waiting for the AGV parking robot to return empty car pallets accumulates, leading to excessively long waiting times for vehicles outside the parking garage, significantly reducing parking and retrieval efficiency. Furthermore, the redundancy in the process results in a poor parking experience for users, making it difficult to meet the demands of modern parking lots for efficient and convenient parking services.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 A stacking machine for storing AGV vehicle pallets, comprising: A support frame for supporting multiple stacked AGV vehicle platforms; A guide component, disposed on the support frame, is used to provide lifting guidance; Lifting component 9, installed on the support frame, is used to lift or lower the AGV vehicle platform under the guidance of the guide component; Synchronization component 10, connected to the lifting component 9, is used to drive the lifting component 9 to move synchronously in order to keep the AGV vehicle platform horizontal; Roller assembly 11, mounted on the support frame, is used to transfer AGV vehicle plates between the stacking machine and the car lift.

[0026] Specifically, the stacking machine uses a support frame as its basic support structure, which carries multiple stacked AGV vehicle pallets to provide a storage base for subsequent continuous pallet supply. Guide components are fixed to the support frame, providing a fixed guide trajectory for the lifting assembly 9's lifting movement, ensuring that the lifting assembly 9 runs smoothly along a preset path. The lifting assembly 9, installed on the support frame, lifts or lowers the AGV vehicle pallets along the guide trajectory of the guide components under power drive, completing the stacking, storage, or retrieval of the vehicle pallets. A synchronization component 10 establishes a transmission connection with the lifting assembly 9, constraining the movement state of the lifting assembly 9, ensuring that all actuators of the lifting assembly 9 move synchronously, guaranteeing that the AGV vehicle pallets remain horizontal during lifting. A roller assembly 11 is located at the vehicle pallet conveying position on the support frame, using the rotation of the rollers to achieve the translational conveying of the AGV vehicle pallets between the stacking machine and the car lift, cooperating with the garage control system to achieve automatic handover of the vehicle pallets.

[0027] In the above technical solution, the stacking machine for storing AGV vehicle pallets uses a support frame to stack and store multiple AGV vehicle pallets. This eliminates the need to wait for the AGV parking robot to return empty pallets from the parking space, directly providing spare pallets for the car lift. This shortens the waiting time in the vehicle storage and retrieval process, effectively improving storage and retrieval efficiency and enhancing the user experience. The guide component provides stable lifting guidance for the lifting assembly 9, and works in conjunction with the synchronization component 10 to drive the lifting assembly 9 to move synchronously, ensuring that the AGV vehicle pallets remain horizontal during lifting and lowering, avoiding structural damage or operational malfunctions caused by pallet tilting. Under the guidance of the guide component, the lifting assembly 9 accurately lifts and lowers the vehicle pallets, while the roller assembly 11 efficiently transfers the vehicle pallets between the stacking machine and the car lift.

[0028] Preferably, the supporting frame includes a column 1, an upper crossbeam 2, a synchronous longitudinal beam 4, a connecting longitudinal beam 3, a lower crossbeam 6, and a lower crossbeam mounting bracket 5; the guiding component includes a guide column 8 and a guide column mounting bracket 7; the upper crossbeam 2 is fixedly connected to the upper end of the column 1, the synchronous longitudinal beam 4 and the connecting longitudinal beam 3 are respectively fixedly connected to both sides of the two upper crossbeams 2, the lower crossbeam mounting bracket 5 is fixedly connected to the lower part of the column 1, and the lower crossbeam 6 is fixedly connected to the lower crossbeam mounting bracket 5 and the column 1; the guide column mounting bracket 7 is fixedly connected to the column 1, and the guide column 8 is fixedly connected to the guide column mounting bracket 7; the synchronous component 10 is drivenly connected to the lifting component 9 to achieve synchronous drive.

[0029] Specifically, the load-bearing frame adopts a modular rigid connection, with four columns 1 as the core support structure. The upper crossbeams 2 are fixedly connected to the upper ends of the columns 1 to form a top support structure. Synchronous longitudinal beams 4 and connecting longitudinal beams 3 are symmetrically connected to both sides of the two upper crossbeams 2, forming a top lateral stability structure to support the top of the lifting assembly 9 and the synchronous assembly 10. The lower crossbeam mounting bracket 5 serves as a transition connector, fixed to the lower part of the columns 1, providing an installation carrier for the lower crossbeam 6, allowing the lower crossbeam 6 to be firmly connected to the columns 1 to form a bottom support structure, thus constructing a complete three-dimensional load-bearing frame. Simultaneously, it supports the roller assembly 11... The circulating sprocket 17 provides the installation reference; the guide column 8 is fixed to the column 1 by the guide column mounting bracket 7, so that the guide trajectory of the guide column 8 matches the movement path of the lifting component 9, ensuring that the lifting component 9 rises and falls smoothly along the guide column 8; the transmission connection between the synchronous component 10 and the lifting component 9 relies on the installation space provided by the synchronous longitudinal beam 4 in the load-bearing frame, so that the synchronous component 10 can form a precise transmission cooperation with the lifting component 9, and the mechanical transmission structure forcibly constrains the movement consistency of the lifting component 9, adapting to the symmetrical structural layout of the load-bearing frame, and ensuring the structural stability during the stacking and lifting of multiple vehicle platforms.

[0030] The lifting assembly 9 includes a drive shaft assembly 12, a drive chain 13, a drive sprocket 14, a drive motor 15, a lifting rod assembly 16, a circulating sprocket 17, and a lifting chain 18. The drive shaft assembly 12 is connected to the upper crossbeam 2, the drive motor 15 is connected to the lower crossbeam 2, and the circulating sprocket 17 is connected to the lower crossbeam 6. The output end of the drive motor 15 is connected to the drive sprocket 14, the drive sprocket 14 is connected to the drive shaft assembly 12 via the drive chain 13, the drive shaft assembly 12 is connected to the lifting rod assembly 16 via the lifting chain 18, and the lifting chain 18 is wound around the circulating sprocket 17 to form a circulating transmission path.

[0031] In the above technical solution, the rotation of the drive motor 15 drives the drive sprocket 14 to rotate synchronously; the drive sprocket 14 establishes a transmission relationship with the drive shaft assembly 12 through the drive chain 13, and transmits power to the drive shaft assembly 12 by means of the meshing characteristics of the chain drive, so that the drive shaft assembly 12 rotates synchronously with the drive sprocket 14; when the drive shaft assembly 12 rotates, it drives the lifting chain 18 on it to move. In order to make the lifting chain 18 form a stable lifting transmission trajectory, the circulating sprocket 17 is fixed under the lower crossbeam 6, so that the lifting chain 18 is wound around the circulating sprocket 17 to form an upper The closed-loop transmission path, with the circulating sprocket 17 serving to both tension the chain and change the transmission direction; the lifting rod assembly 16 is fixedly connected to the lifting chain 18. When the lifting chain 18 moves under the drive of the drive shaft assembly 12 and the guidance of the circulating sprocket 17, it drives the lifting rod assembly 16 to perform linear lifting and lowering movements along the guide component, thereby achieving the lifting or lowering action of the AGV vehicle platform; the vertically corresponding installation of the drive shaft assembly 12 and the drive motor 15 is to ensure that the drive chain 13 is transmitted vertically, reducing horizontal offset during transmission and ensuring the accuracy of power transmission.

[0032] Specifically, the drive shaft assembly 12 includes a drive shaft 19, a second drive sprocket 20, a lifting sprocket 22, and a seated bearing 21. The second drive sprocket 20 is fixedly sleeved in the middle of the drive shaft 19. A first drive sprocket 14 is connected to the second drive sprocket 20 via a drive chain 13. Two lifting sprockets 22 are fixedly sleeved at both ends of the drive shaft 19 and located on both sides of the second drive sprocket 20. Sealed bearings 21 are provided on both sides of each lifting sprocket 22. The drive shaft 19 is fixedly connected to the upper crossbeam 2 via the seated bearings 21. The lifting sprockets 22 mesh with the lifting chain 18 to drive the lifting chain 18 to rise and fall. The drive motor 15 rotates, driving the first drive sprocket 14 to rotate. The first drive sprocket 14 drives the second drive sprocket 20 to rotate via the drive chain 13. The drive shaft 19 and its lifting sprockets 22 also rotate accordingly, driving the lifting chain 18 and the lifting rod assembly 16 to rise or fall.

[0033] Furthermore, the second drive sprocket 20 is fixedly sleeved in the middle of the drive shaft 19, making it a power receiving node. Through the engagement of the drive chain 13 and the first drive sprocket 14, power is precisely transmitted from the drive motor 15 to the drive shaft 19. To ensure synchronous power transmission to the lifting chains 18 on both sides, two lifting sprockets 22 are symmetrically fixedly sleeved on the drive shaft 19 on both sides of the second drive sprocket 20, forming a symmetrical power output structure. This ensures that the lifting chains 18 on both sides receive balanced driving force, structurally guaranteeing the synchronous lifting and lowering of the lifting rod assembly 16. Considering that the drive shaft 19 needs to simultaneously bear the dual requirements of power transmission and radial support, bearings 21 with seats are respectively installed on both sides of each lifting sprocket 22. The inner ring of bearing 21 mates with drive shaft 19, and the outer ring is fixedly connected to the upper crossbeam 2. This not only provides rotatable support for drive shaft 19, but also reduces the rotational resistance of drive shaft 19 through the rolling friction characteristics of the bearing. At the same time, the integrated design of bearing 21 with seat facilitates installation and positioning, and ensures the coaxiality of drive shaft 19. When drive motor 15 drives drive sprocket 14 to rotate, the power is transmitted to drive sprocket 20 through drive chain 13. Drive sprocket 20 drives drive shaft 19 to rotate synchronously. The lifting sprockets 22 at both ends of drive shaft 19 rotate with drive shaft 19. Through meshing transmission with lifting chain 18, they drive lifting chain 18 to rise and fall, ultimately realizing the rising or falling action of lifting rod assembly 16.

[0034] The lifting rod assembly 16 includes a lifting rod 28 and bolt-type rollers 29. The lifting rod 28 is fixedly connected to the lifting chain 18. Multiple bolt-type rollers 29 are provided, and the multiple bolt-type rollers 29 are rotatably installed on both sides of the lifting rod 28. The bolt-type rollers 29 roll with the guide post 8 to achieve guidance. Two bolt-type rollers 29 are provided on both sides of each lifting rod 28, and the two bolt-type rollers 29 are arranged at intervals along the length direction of the lifting rod 28. The outer wall of the guide post 8 is provided with a guide groove extending along the length direction, and the bolt-type rollers 29 are embedded in the guide groove and roll along the guide groove.

[0035] In the above technical solution, the lifting rod assembly 16 uses the lifting rod 28 as the rigid load-bearing body. Through the fixed connection with the lifting chain 18, the power is directly transmitted, which can stably support the weight of the AGV vehicle platform and move up and down synchronously with the lifting chain 18. Two lifting rods are provided on each side of each lifting rod 28 and are distributed at intervals along the length direction, forming a multi-point rolling guide structure. With the guide groove extending along the length direction on the outer wall of the guide post 8, the bolt-type roller 29 can constrain the movement trajectory of the lifting rod 28 from multiple dimensions when it is embedded in the groove and rolls, thus improving the guiding accuracy. Compared with the sliding fit, the rolling fit can reduce frictional resistance and reduce the wear of the bolt-type roller 29 and the guide post 8. At the same time, it makes the lifting rod assembly 16 move up and down more smoothly and avoids jamming.

[0036] The synchronization assembly 10 includes a synchronization shaft 23, a synchronization sprocket 24, a synchronization gear 25, a synchronization chain 26, and an adjusting rod assembly 27. The synchronization sprocket 24 includes a drive-end synchronization sprocket and an intermediate synchronization sprocket. The drive-end synchronization sprocket is fixedly sleeved at both ends of the drive shaft 19, and the intermediate synchronization sprocket is rotatably mounted in the middle position of the synchronization longitudinal beam 4. The drive-end synchronization sprocket is connected to the intermediate synchronization sprocket via the synchronization chain 26. The synchronization shaft 23 is fixedly inserted through the intermediate synchronization sprocket. There are two synchronization gears 25, which are respectively fixedly sleeved at both ends of the synchronization shaft 23 and located on the synchronization longitudinal beam 4. The two synchronization gears 25 mesh with each other to achieve bidirectional synchronization. A bearing seat is fixedly installed inside the synchronization longitudinal beam 4, and the synchronization shaft 23 is rotatably connected to the synchronization longitudinal beam 4 via the bearing seat. The adjusting rod assembly 27 is fixedly connected to the lifting rod assembly 16. When the lifting rod assembly 16 is raised or lowered to its limit position, the bolt-type roller 29 disengages from the guide post 8.

[0037] In the above technical solution, the synchronous longitudinal beam 4 is used as the mounting carrier. The synchronous sprockets at the drive end are fixedly sleeved on both ends of the drive shafts 19 on both sides, so that the rotation of the drive shafts 19 can be directly transmitted to the synchronous sprockets at the drive end. The intermediate synchronous sprocket is installed in the middle of the synchronous longitudinal beam 4 and establishes a transmission connection with the synchronous sprockets at both drive ends through the synchronous chain 26, forming a linkage bridge of power on both sides. The synchronous shaft 23 is fixedly inserted through the intermediate synchronous sprocket, converting the rotation of the intermediate synchronous sprocket into the rotational power of the synchronous shaft 23. The two synchronous gears 25 fixedly sleeved at both ends of the synchronous shaft 23 mesh with each other. When the speed of one drive shaft 19 fluctuates, the speed deviation is fed back to the other drive shaft 19. 9. Forcefully correct the difference in rotational speed on both sides to achieve absolute synchronization of the two lifting components 9; the bearing seat in the synchronous longitudinal beam 4 is precisely matched with the synchronous shaft 23, and the rolling support reduces the rotational resistance of the synchronous shaft 23, while ensuring the coaxiality of the synchronous shaft 23 and ensuring the precise meshing of the synchronous gear 25; the adjusting rod assembly 27 is adapted to the limit stroke requirements of the lifting rod assembly 16, and its fixed connection with the lifting rod assembly 16 makes the movement of the two completely synchronized. When the lifting rod 28 is raised or lowered to the limit position, the adjusting rod assembly 27 drives the bolt-type roller 29 to disengage from the guide column 8, and the component protection is achieved through the stroke limit of the mechanical structure, which is adapted to the transmission and guidance coordination requirements of the overall equipment.

[0038] The column 1 has four columns, which are centrally symmetrically distributed; the lifting assembly 9 has two components, which are symmetrically installed on both sides of the synchronous longitudinal beam 4, and the drive shaft 19 of the two lifting assemblies 9 are connected to the synchronous assembly 10 for transmission.

[0039] The synchronous longitudinal beam 4 has an internal mounting cavity, in which the synchronous shaft 23, synchronous gear 25 and synchronous sprocket 24 are all housed; the two drive end synchronous sprockets are driven by two synchronous chains 26 respectively meshing with the two sides of the middle synchronous sprocket.

[0040] The roller assembly 11 includes a roller, a roller shaft, and a roller bracket; the roller bracket is fixedly connected to the lower crossbeam 6, the roller shaft is rotatably mounted on the roller bracket, and the roller is fixedly sleeved on the roller shaft; the top surface of the roller is higher than the top surface of the lower crossbeam 6, and the rotation direction of the roller is consistent with the conveying direction of the AGV vehicle platform.

[0041] Specifically, using the roller bracket as the installation carrier, its fixed connection with the lower crossbeam 6 relies on the stability of the lower crossbeam 6 as a key component at the bottom of the load-bearing frame, providing a precise and stable installation benchmark for the roller shaft and rollers, ensuring the parallelism of the roller axis and the consistency of the installation height; the rotational connection between the roller shaft and the roller bracket uses rolling bearings to achieve low-resistance support, allowing the roller shaft to rotate flexibly, and the rollers are fixedly sleeved on the roller shaft to form a synchronous rotation structure, converting the rotation of the roller shaft into the translational force of the vehicle platform; the top surface of the roller is higher than the top surface of the lower crossbeam 6, so that the roller only contacts the bottom of the vehicle platform, forming a line contact rolling support, which reduces the contact area to reduce frictional resistance, and the even distribution of multiple rollers ensures the stable support of the vehicle platform; according to the relative position of the stacking machine and the car lift and the vehicle platform transfer path, the rotation direction of the rollers is preset and the directional rotation is achieved through the installation orientation of the roller shaft, ensuring that the vehicle platform is transferred along the preset straight line direction.

[0042] The working principle and usage process of this utility model are as follows: In the initial state, the load-bearing frame of the stacking machine is stably supported by four centrally symmetrically distributed columns 1 and upper and lower crossbeams 6. Multiple AGV vehicle plates are stacked on the lifting rod assembly 16. The bolt-type rollers 29 of the lifting rod assembly 16 are embedded in the guide grooves of the guide columns 8. The transmission components of the synchronization assembly 10 are in a ready-to-trigger state. The top surface of the rollers of the roller assembly 11 is higher than the top surface of the lower crossbeam 6 and remains ready. When the AGV parking robot leaves the car lift with the vehicle plates and the vehicles on them, the garage control system issues a command, and the rollers of the roller assembly 11 move along the direction of the vehicle plate transport under the drive of the roller shaft. The rotating mechanism smoothly transfers the bottommost spare AGV vehicle platform from the stacking machine to the car lift. After the AGV vehicle platform touches the limit switch on the car lift, the drive motor 15 of the lifting assembly 9 starts and drives the drive sprocket 14 to rotate. The drive sprocket 14 drives the drive sprocket 20 of the drive shaft assembly 12 to rotate via the drive chain 13, causing the drive shaft 19 to rotate synchronously with the drive sprocket 20. The lifting sprockets 22 at both ends of the drive shaft 19 then rotate, driving the lifting chain 18 and the lifting rod assembly 16 to descend along the guide column 8. Simultaneously, the synchronization assembly 10 begins operation: the drive end synchronization sprockets at both ends of the drive shaft 19 drive the synchronous chain 26... The intermediate synchronous sprocket inside the mounting cavity of the synchronous longitudinal beam 4 rotates, and the synchronous shaft 23 rotates with the intermediate synchronous sprocket. The synchronous gears 25 at both ends of the shaft rotate together to force the drive shafts 19 on both sides to rotate at the same speed, ensuring that the lifting rod assembly 16 descends horizontally. During the descent of the lifting rod assembly 16, the bolt-type rollers 29 on both sides roll along the guide grooves of the guide post 8 to achieve precise guidance until the remaining AGV vehicle plates in the stacking machine fall onto the roller assembly 11 for standby. The drive motor 15 continues to rotate to lower the lifting rod assembly 16 to its limit position. The adjusting rod assembly 27, which is fixedly connected to the lifting rod assembly 16, drives the bolt-type rollers 29 to disengage from the guide post 8 to protect the components. When the car lift needs to replenish the AGV vehicle platform again, the garage control system issues another command. The roller assembly 11 repeats the transfer action to move the new spare vehicle platform to the car lift. Then, the drive motor 15 rotates in the opposite direction, driving the lifting rod assembly 16 to rise and reset through the drive chain 13, drive shaft assembly 12, and lifting chain 18. The bolt-type roller 29 is re-embedded in the guide groove of the guide column 8. The synchronization assembly 10 ensures that the lifting rod assembly 16 rises horizontally through synchronous transmission. After the lifting rod assembly 16 supports the remaining stacked AGV vehicle platforms, it stops, completing one replenishment cycle. The above process is repeated to achieve a continuous supply of AGV vehicle platforms.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
